A convicted methamphetamine dealer was found hanging in his cell in the Osceola County Jail over the weekend and is thought to have committed suicide, authorities said Monday.

The Osceola County Sheriff's Office received a call about 9 p.m. Saturday stating that the cellmate of Russell Leigh Smith, 45, had found him hanging, said Twis Lizasuain, a sheriff's spokeswoman.

Deputies are investigating what time the incident happened and what time it was discovered. They would not disclose details.

Smith, of St. Cloud, pleaded guilty in September to two counts of aiding and abetting others to possess with intent to distribute methamphetamine. He was sentenced Jan. 12 to three years and four months in federal prison.

He introduced a Kissimmee man to an undercover Osceola drug agent who bought methamphetamine five times from an associate of Smith, prosecutors said. The seller, Casey Lee White, 49, of Intercession City, was sentenced last month to 10 years in federal prison.

Two other Osceola County men and one man from Orlando also got prison time in the case.

Smith was in jail awaiting trial on another drug case, a county spokesman said.

He was sentenced to 15 months in state prison and three years of probation in 2005 for burglary and released in November of that year.
